A Comprehensive Approach: Correlating Ultrasound Imaging with Endometrial Histopathological Analysis in Perimenopausal Women with Heavy Menstrual Bleeding

Abstract

INTRODUCTION Abnormal uterine bleeding (AUB) is a common troublesome symptom in the perimenopausal age group. The most common type of AUB in this age group is heavy menstrual bleeding. There is a risk of endometrial carcinoma and atypical endometrial hyperplasia in women with AUB in the age group of 40-50 years. Hence early evaluation is of paramount importance in managing women with perimenopausal heavy menstrual bleeding. The current study was undertaken to study the correlation between ultrasound findings and various benign and malignant endometrial histologies in perimenopausal women with heavy menstrual bleeding. METHODOLOGY Women aged 40-55 years presenting with heavy menstrual bleeding at the gynaecology outpatient department at Sree Balaji Medical College and Hospital, Chennai, India, were included in the study. Patients on anti-platelet and anti-coagulation therapy and patients already on hormonal treatment for heavy menstrual bleeding were excluded from the study. The demographic factors, symptom profiles, ultrasound findings, and histopathological reports were tabulated and analysed. RESULTS Of the 147 women included in the study, 75 (51%) were aged 45-50 years and 107 (73%) had two or more pregnancies. Fibroid was the common non-endometrial cause of heavy menstrual bleeding in 52 (35%) cases. The proliferative pattern was the most common non-pathological histology identified in 46 (31%) cases. Endometrial hyperplasia without atypia was the most common pathological histology observed in the study population. Endometrial thickness of more than 8 mm was strongly associated with premalignant or malignant endometrial lesions. CONCLUSION Our study has attempted to identify the correlation between ultrasound evaluation of perimenopausal women with heavy menstrual bleeding and endometrial pathology. Ultrasound, being cost-effective and widely available, is proven to be a tool for first-line investigation of perimenopausal women with heavy menstrual bleeding that guides further evaluation and management.
